Abstract
This paper discusses the design of low-voltage low-power fully-integra table automatic gain controls. Four different AGCs are presented, all consisting of three elementary building blocks: a controlled amplifier , a comparator and a voltage follower. Their design is treated separat ely. As an example, the final section describes an automatic gain cont rol for hearing instruments, realized in a bipolar process.
